ROCK-CRUSHER.

T 0 all whom it may concern:

Be it known that I, EDWIN S. PHILIPS, a citizen of the United States,residing at Kennett Square, county of Chester, and State ofPennsylvania, have invented a new and useful Improvement inRock-Crushers, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

The object of my invention is to provide a rock-crusher adapted to beconverted from a crusher of large capacity to one of relatively smallcapacity, and vice versa, in accordance with the amount of work at anygiven time to be done. Heretofore it has been customary for the user tohave on hand a plurality of separate crushers, one only being used whena relatively small amount of stone was required to be crushed, while theremaining crusher or crushers was brought into use when the amount ofstone to be crushed increased beyond the capacity of a single crusher.

My invention consists in a duplex crusher provided with a single fixedjaw and a plurality of movable jaws, each having separate andindependent actuating mechanism, arranged on opposite sides of the fixedjaw, as hereinafter claimed.

My invention also consists in certain novel features of constructionapplied to the fixed jaw and hopper and certain novel features ofarrangement of the same with respect to the moving parts, as hereinafterclaimed.

In the drawings Figure 1 is a plan view of the crusher with a hopperremoved. Fig. 2 is a section on the line 2-2 of Fig. 1.

Certain details of construction are omitted from the drawings anddescription, as they are known in the art and form no part of myinvention.

10, 10 are the side plates of the machine between which the operativeparts of the crusher are secured.

11 is the fixed jaw member carrying on opposite sides dies 12, 12.

13, 13, are the movable jaws arranged 011 opposite sides of the fixedjaw and carrying dies 14, 14 arranged opposite, and cooperating with,the dies 12, 12, respectively of the fixed jaw. The movable jaws arependulous from the fixed shafts 15, 15, respec- Specification of LettersPatent.

tively, extending between, and secured to, the side plates from theoutside.

At each end of the crusher is a shaft carrying the cam 16. Thiscam-shaft ro tates in bearings secured to the outside of the side-platesand carries the fiy-wheels 17, which serve as belt-wheels for drivingthe corresponding end of the crusher and also as traveling wheels intransporting the crusher from place to place. Each cam 16 actuates atumbler roller 18, whose axle revolves in bearings in side-flanges 19 onthe upper and outer end of a tumbler-lever 20.

Each tumbler-lever 20 at its lower and inner end surrounds and issecured to a shaft 21 by means of a set screw 22 extending through thetumbler-lever and engaging a flattened face of the shaft. The shaft isflattened on opposite sides so that it may be reversed to compensate forwear. The shaft 21 oscillates in bearings secured to the outside of theside-plates. The upper and outer end of each tumbler-lever 20 is heldagainst its actuating cam 16 by means of a compression spring 23confined between this end of the tumbler-lever and a casting 24: securedbetween the side-plates.

The opposing faces of the moving aws 13 and their correspondingtumbler-levers 20 are provided with clove-tail recesses within which arefitted the toggle-seats 25. The toggles 26 are seated at their oppositeends in the toggle-seats 25.

At each end of the crusher, adjacent to the inner walls of theside-plates, are plates 27 supported on bolts 270 passing through andextending between the side-plates. Bolted to each plate 27 is thedepending T- bar 28. A rod 29 extends from each side of the lower freeend of the moving jaw 13 and extends through the corresponding T- bar28. A spring 30 is confined between the T-bar and a nut 31 threaded onthe outer end of the rod. The function of these springs and rods is tohold each moving aw in operative relation with its correspondingtumbler-lever. I

Each die 1ft is set into a recess in the face of the moving jaw 13. Awedge-shaped orifice extends through the jaw on each side of its center,the lower part of the orifice opening into the die-recess and its upperpart alining with a groove formed in the overhanging part of the jawabove the die're provided a hopper as whose inwardly in cess. thisgroove and recess and also into a groove in the upper end of the die lt. The rear end of the key is circular in shape and is threaded toreceive anut 33 and washer 34E abutting against the back of the die andby means of which the key 32 may be drawn inwardly to securely confinethe die in its recess.

35, 35, are reversible and interchangeable cheek-plates or linerssecured to the side plates opposite the crushing faces of the dies.These plates protect the side-plates from wear due to the crushing ofstone.

The fixed jaw 11 is provided at each side with vertically extendingtongues 38 extending into vertical grooves 87 formed on the inner wallsof the side-plates. The jaw 11 is securely held between the side platesby means of bolts 38 extending from one side plate to the other andentirely through the jaw. The fixed jaw is also provided with pockets inits lower face, in which are the heads of bolts 39. These bolts extendoutwardly through the adjacent part of the jaw and through theside-plates and are tightened by means of nuts. The upper face of thejaw is provided with pockets 41 and bolts 42 extend from these pocketsoutwardly through the jaw and the side-plates and are tightened by meansof nuts $3.

The dies 12 are held in position by means similar to the means forholding in place the dies lat of the moving jaws 13. edgeshaped orificesextend outwardly from the pockets 41 through the aw, the upper parts ofthe orifices alining with grooves formed in the part of the jawoverhanging the die. Into each orifice and its corresponding grooveextends a wedge-shaped key 4.4., which also extends into a groove in theupper end of the die. By means of the nut 15 on the inner end of thekey, the same is drawn inwardly, causing the upper face of the key topress against the aw and the inclined lower end to press against thedie, thereby securely holding the die in its recess.

superposed on the fixed jaw is a cap 46. This cap, besides entirelyoverlying the jaw, extends down to the die-recesses. Above the key-ways,the cap is cut away on the inside to permit the jaw to be enlarged atthese points for the purpose of lengthening the bearing surface of thekeys 41 against the jaw. The lower edges of the cap are also groovedacross at these points, these grooves alining with the grooves in thejaw to permit the keys to be inserted in their ways.

The cap is held on the fixed jaw by means of bolts 4L7. The heads of thebolts are seated in a recess formed by cutting away the cap and jaw andthe shank of the bolt extends through a groove formed in the under faceof the cap.

To feed the material to the jaws there is A wedge-shaped key 82 extendsinto clined end walls extend over, and down in front of, the pivotedupper ends of the moving jaws respectively, and whose side walls inclineinwardly toward the side-plates and thence extend vertically downwardlyalong the inner walls of the side plates and terminate at the upper endsof the cheek-plates The upper face of the cap slopes downwardly from itscentral part toward the dies 12, 12, respectively, thereby, inconjunction with the hopper, guiding the material bet-ween both sets ofcrushing dies.

Heretofore, when two single crushers have been used together, they haveoften been arranged end to end so as to enable them to be fed togetherfrom dump carts or dump cars. This arrangement has never workedsatisfactorily, owing to the fact that there are two separate anddistinct and relatively small openings, 2'. 6., the spaces between thefixed jaws and their corresponding movable jaws, to receive the stone,and the stone con sequently often bridges or arches over one or bothopenings, which clogs the opening and renders the crusher inoperative.In my invention, however, the two receiving openings are so closetogether as to form virtually a single wide opening, so that when thematerial is dumped into the single hopper spanning the space between themovable jaws, there is much less likelihood of the material becomingclogged in the opening. The liability to clogging is also lessened byconstructing the cap forming the upper part of the fixed jaw so that itsopposite sides slope downwardly toward the two movable jaws.

Either end of the crusher can be thrown out of operation at will, andthe end in operation will crush the same amount of mate rial as a singlecrusher of normal capacity, but it is obvious that its cost ofconstruction is substantially less than the cost of construction of twosingle crushers, and besides is more economically transported from placeto place. hen the crusher as a whole is operated, it will have the samecapacity as two single crushers of normal capacity or the same capacityas an ordinary crusher having a double width of aws. When both ends ofthe crusher are in use, the advantage over an ordinary crusher of thesame capacity is that the strain upon the fixed aw in either directionis only half the strain upon the fixed jaw of the ordinary crusher andwhat strain there is in one direction is counterbalanced by an equalstrain in the opposite direction.

\Vhile the movable aws are independently operated by their actuatingmechanism, it must not be understood that the latter need be driven froma separate source of power. On the contrary, the more convenient methodof driving would be to drive both crushers from the same engine bybelting the engine pulley to the fiy-wheels of one crusher and thenbelting the engine pulley to the flywheels of the other crusher by meansof belts overlying the firstnamed belts; it being understood there willthus be two driving belts for each crusher or four belts in all.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is 1. In a rock-crusher, the combination withside plates, of shafts between the side plates, movable jaws pendulousfrom the shafts, a fixed jaw between the movable jaws, a cap surmountingthe fixed jaw and havin sides sloping toward the movable jaws, said capbeing located below the level of the tops of the movable jaws, and ahopper above the cap having side walls extending in front of thependulous upper ends of the movable jaws and forming with said cap aplurality of passages for the delivery of material to be crushed onopposite sides of the fixed jaw.
